This TDC (Top Down Centre) Trolley is designed for Maxx Hop-up chambers to incorporate the use of tensioner nubs in flat hop builds (some R-hop set-ups may also work)

Depending on the specific nub used this can help with consistency, accuracy or increasing range.

The TDC trolley ensures an evenly distributed force is applied onto the bucking down to the flat hop or r-hop patch. This ensures the patch can maximize its effect on the BB for the most stable and uniform spin.

The trolley works well with flat hop, Maple Super Macaron and MR hop buckings.
